Police officers investigating the killing of Reeva Steenkamp have compromised important evidence by removing it from the crime scene, South African television has claimed.

The bathroom door through which Oscar Pistorius fired at his girlfriend was taken away from the sprinter’s home four days after the shooting - before his forensics experts had the chance to examine it at the scene, the reports say.

This ITV News report from February 20 explains the significance of the door:

Specialists working for the sprinter were eventually allowed to “look at but not touch” the door at a police station, but the experts should have had the opportunity to study it at the athlete’s home, according to broadcaster ENCA.
